This study reports two untreatable cases of palatal radicular grooves in maxillary lateral incisors. A unique canal configuration was discovered in one case, offering new insights into this rare dental anomaly.

Area of Science:

  • Dentistry
  • Endodontics
  • Dental Anatomy

Background:

  • Palatal radicular grooves are rare developmental anomalies affecting maxillary incisors.
  • These grooves can complicate endodontic treatment and prognosis.
  • Understanding their morphology is crucial for effective clinical management.

Observation:

  • Two cases of palatal radicular grooves in maxillary lateral incisors were identified.
  • Both cases were initially deemed untreatable due to the anomaly's severity.
  • Detailed analysis included horizontal sectioning of one affected tooth.

Findings:

  • The palatal radicular groove is a rare anomaly impacting maxillary lateral incisors.
  • A previously unreported canal configuration was observed within the radicular groove.

  • This finding highlights the complex internal anatomy associated with such anomalies.

    • Implications:

    • The findings expand the understanding of root canal anatomy in the presence of palatal radicular grooves.
    • This knowledge may inform treatment planning and prognosis for similar rare dental anomalies.
    • Further research into the prevalence and management of palatal radicular grooves is warranted.
